How much snow accumulates in North America each year? More than scientists thought

Scientists have revised an estimate of snow volume for the entire continent, and they’ve discovered that snow accumulation in a typical year is 50 percent higher than previously thought. Researchers at The Ohio State University place the yearly estimate at about 1,200 cubic miles of snow. If spread evenly across the surface of the continent from Canada to Mexico, the snow would measure a little over 7.5 inches deep.
